4 Claims.

This invention relates ,to rotary sprinklers, andy provide large surface area' over which is sprinkled a liquid suclras hard. cider, so lthe -alcohol in the liquid may be readily converted into acetic acid. The purposejof the sparger is to distribute the liquidevenly over the material injthe vat or receptacle.

One object of this invention is to provide avery simple form of rotarysprinkler or sparger which consists of comparatively few, and ysimple parts, so it can be manufactured at a comparatively low cost.

lAnother object kis to provide an improved sparger which has a self .regulating feature to prevent excessive speedfof rotation, at the same time preventing waste ofthe liquid being sprinkled or distributed.

Another object' is to 'provide an improved sparger of materials which are proof against corrosion and other detrimental effects of the acid in the cider "and of the fumes from the acetic acidlf Y f Other obj ects and important features are pointed out orv implied inthe following details' of de-v scription in connection with the accompanying drawing in which: v

Fig'. 1 is a top plan view of my improved sparger. Fig. 2 is a view partly in side elevation', and partly in central vertical-section.

Referring to the drawing in detail, in which similar reference characters correspond with similar parts in the several views, the invention is described in detail as follows:

A funnel-like receptacle 5 has its lower end internally threaded at 6, and within this threaded aperture is fitted the screw-threaded lower end portion of a vertical tube 7 which has a vertical slot 'la in its intermediate part, the lower end of this slot terminating at the bottom of the receptacle 5. The upper end of the tubular member '7 has a plug 8 secured therein, by solder or other appropriate means 9, and this plug 8 is centrally apertured to provide a bearing ofl a pivot-rod 10. The upper end of this pivot-rod is secured in an apertured Wall of a feed-pipe 11 through which the cider passes from a tilting receptacle or other intermittent feeding device (not shown). Solder or welding material 12 may be employed for securing the pivot-rod 12 in a iixed position.V It has 11 and the tube '7L s1. serialy No. 52.8;184 I (o1. 299-69.), y

a' `bent',intermediate part, so that its lower' end isvertical and'axially alined `with the feed-*pipe Alock-nut 13 is threaded on thetube 7, and

`bears against the lower end of the receptacle 5,

for holding it in xed relation to the tube 7.

A special 'form of T-pipe or' hollow connection 111 is threadedV onl .the lower end of the tube 7, and has an .apertured boss 15 in which is secured a 'pointed pivot 16. 1A pivot-bearing 17, preferably of glass, is secured to a supporting bar 18A which may have its ends resting on opposite sides of the'vat or container of 'the material to' be l sprinkled. l Y

f The T-pipe or connection 14 has laterally apertured sprinkler-tubes 19 'screwed therein, and the ends of these tubes are plugged as indicated at 20. The apertures 21 of one Aoi the tubes 19 are on opposite sides from that of the similar apertures of ',.the 'other tube. Therefore, the liquid will'flow` in opposite directions, and such flow will cause the sparger to rotatewhile the liquid is owing, by the reacting force which is well understood by those who are -,familiar with the art. The purpose of spacing the apertures 21 nearer and nearertogether fromthe inner tothe outer ends of the tubes 19, is also well understood by persons r familiarr with the art, asllobtai'ningfthe most even' distribution of theliquid.

The upper and intermediateparts of the tube 7 havetwo `important functions, vthat is, as a pivot-bearing at 8-10, andas a ,regulating feature at 7a,-in` connection with vthe upwardly inf clined wall of the receptacle'li'. yIn this latter connection, assume that the receptacle is nearly' full of cider, that the cider is flowing through the slot 7a, thence through the lower part of the tube '7., into the parts 14 and 19, and out through the apertures or jet-openings 21, and that the spar' ger Vbegins to rapidly rotate. to such an extent that the sprinkling would be excessive atrthe outer part of the material being sprinkled, while no sprinkling would be done at the central part, because of the centrifugal force'. gal force also tends to throw the cider against the inclined wall of the receptacle 5, and by such action to raise the liquid in the receptacle, so as to reduce the pressure at the slot 7a, andthereby reduce the force which tends to turn the sparger. F

funnel-like receptacle 5, by thev capacity of the 2110 slot 7a, and by other relative dimensions of the device and of the apertures thereof.

The tubes and T-connection as well as the parts 5, 8 and 13, may be of hard rubber or other non-metallic and non-corrosive materials; and inasmuch as these can not be very tightly screwed together, because of the danger of breaking them,

Vit is` desirable that a practical and eiective supof the rods 22 extend through openings 24 andare'bent to secure them against outwardtmovement. The lower ends of these rods are curved around the lower sides of the tubes 19 and ,se-

cured thereto as indicated at 25, so asto support the outer ends of these rods; `and 4at the same time prevent them from becoming unscrewed by accident. The intermediate parts or" the rods 22 are formed with loops 26, which are engaged with loops 27 of the rods 23. 'Th-ese latter rods have their lower ends secured to the tubes 19 in the same manner explained with regard to the rods' 22. A

Although I have describedjthis form of my invention specifically, I have no intention of limiting my patent protection to these exact details oi construction, arrangement, or materials, for the invention is susceptible of numerous changes within the scope of the inventive ideas Y as implied and claimed.

What I claim as my invention is:

1. In a rotary sprinkler, the combination of a funnel-likeY receptacle, a vertical tube longitudinally centered inthe axis of rotation vand provided with a vertical pivotal connection at its upper end, said tube extending through and closing the,Y lower convergent end of said funnel -like receptacle and united therewith and `having an opening at a point above and near the bottom of said receptacle vfor permitting liquid to pass from the receptacle to the interior of sadtube, a hollow connection united with the lower end of said vertical tube and in open communication therewith and provided witha vertical pivot, and sprinkler-tubes .united withthehollow connection and in open communication therewith and extending horizontally in opposite directions, each of said sprinkler tubes having its outer end closed and having a series of jet-openings along one of its sides, the jet-openings of one sprinkler-tube being on the opposite side from those of the other sprinkler-tube, substantially as shown, for lthe purposes specified.

2. The structure dened by claim 1, a liquidsupply pipe having an outlet in its lower end and directly over the upper pivotal connection of said vertical tube, the latter having its upper end closed by the upper pivotal connection, the said upper pivotal connection including a pivot-rod united with the wall of said liquid-supply pipe, whereby the latter performs the dual function of supplying liquid to the sprinkler and helping to support the sprinkler. Y

3. In a, rotary sprinkler, the combination of a funnel-like receptaclaa vertical tube having a pivotal connection at its top, said tube extendmg substantially from the top to and through the bottom ofthe funnel-like'receptacle and closing said bottom and having an opening at said bottom to permit liquid to pass from the receptacle to the interior of said vertical tube, a hollow connection on the lower end of said vertical tube and lhaving a pivotal connection on its under side, sprinkler-tubes screwed into said hollow connectionandextending horizontally and having jetopenings positioned for causing rotation of the sprinkler about said' pivotal connections, and rods each .connected to said receptacle and to one of said sprinkler-tubes in proper relation for supporting the ends of the sprinkler tubesl and preventing the sprinkler-tubes from accidentally` unscrewing.

4. In a rotary sprinkler, the combination of a receptacle for liquid, said receptacle having an inverted-conical wall, aV vertical tube extending through the receptacle in concentric relation to the axis of rotation, said receptacle and tube being intimately united in such relation that the wall of the receptacle is imperforate at its bottom, means .independent of said tube for supplying liquid to said receptacle in the space around said tube, a hollow connection secured to the lower end of said tube under said bottom and in open communication with said tube, sprinkler tubes united with said hollow connection and in open communication therewith and extending oppositely therefrom, said sprinkler tubes .having outlet` openings in proper relative positions for imparting rotary motion to said sprinkler about said axis, pivotal connections valined with said axis at the upper and lower ends of the sprinkler, the said vertical tube having a lateral vertical slot through which its interior communicates with the space therearound in said receptacle, whereby more fluid' mayv iiow through the device if there is a tendency of the device `to slow down in its rotation.
